Evaluating the Performance and Delay in Unstructured Peer to Peer Networks

Peer-to-Peer computing has become a popular networking paradigm for file sharing, distributed computing, collaborative working, etc. The widely used unstructured Peer to Peer protocols mainly face problems affecting their working efficiency. Topology mismatch problem between the Overlay network and its underlying network. The authors propose a novel topology Self-Adaptive Topology Matching. In this method, each joining peer is initially guided to find a physically close neighbor to connect with each other. After then, its overlay location is adaptively adjusted whenever a location mismatch is detected.
